Macbookpro 5.1: what is the small button left side close to front with green lights?
This is embarrassing. I've had this computer for 4.5 years, and I just noticed a button that I never saw before (the guy lives in a fog!). I'm wondering what I'm missing (or what I did when I pushed the button). Anybody know?
